Weidner said about 50 firefighters from 12 surrounding departments responded to the blaze.

Those crews eventually pulled back and appeared to be content with letting the fire burn itself out. More than four hours after it began, the fire continued to burn but remained contained to the outline of the one building.

The facade of a neighboring building also appeared burned but that building remained standing.

Weidner said the fire marshal's determination for a cause likely won't be ready today.
